Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral solution only, or in an inert medium, such as perlite or gravel. The nutrients in hydroponics can be from fish waste, normal nutrients, or duck manure.Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium (known as geoponics)
